Interlocked Squares is a club that dances the C-1 program. We dance almost every Thursday evening.

Our regular dance location is Murphy Park in Sunnyvale. But we may sometimes need to dance at a different location (sometimes with changes at the last minute), so it's always a good idea to check the calendar page for this week's location. See the locations page for maps and directions.

Our class that started in 2021 has finished. Our schedule is now full C-1 7:00-9:30pm, with the last two tips (starting at 9:00pm) generally being harder and/or faster.

For information about our classes see the class page. If you would like to receive updates about future classes, write to info@interlocked.org.

We require proof of vaccination against COVID-19 and a waiting period before returning to dancing for anyone who has become infected. (For details see the note at the top of the calendar page.) In addition, we strongly encourage (but no longer require) wearing of N95 or similar masks.

We welcome singles, couples, straight or gay. We use a rotation system for most tips. Dress is casual.

Our staff callers are Bill van Melle, Joe Dehn, and Mary Gingell. When we don't have a class in progress, we also schedule a regular rotation of guest callers.

We have been dancing in the Silicon Valley area for more than 20 years, at locations in San Jose, Cupertino, Palo Alto, Mountain View, and Sunnyvale.
